I'm making a C++ code editor application using VB.NET. I'd like to change the color of the keywords as the user types it. Also I'm looking for a way to highlight some lines of the code.
Is there a way to change the forecolor and backcolour of a piece of text inside a textbox or a rich textbox?
The title says it all, I'm having some difficulties with the combobox, The items in the list are "Black & Green" - Black will be the Backcolor of a Text box, and Green will be the Forecolor.The App I made is just a Mimic of a CMD, and replicates the output of the command into the Textbox. It's 100% complete, but I'd love it to have the ability to have different colors to choose rather than White and Black.

At design time, everything is ok but during the run time, I cannot see the text of labels / groupboxes.
I have an ap that requires the user to fill in information in certain areas in a richtext box. The areas that the user needs to complete is colored blue. To give the user some cue that input is required, I would like to change the mouse pointer when the pointer moves over blue text in the rtb.

View 2 RepliesI've been tingling with the colors of listviewitems.For the most part, they work great, but I can't set alpha:
Me.BackColor = Color.FromArgb(100, 40, 40, 40)
Me.ForeColor = Color.FromArgb(1, 255, 255, 255)
Me.BackColor = Color.FromArgb(100, 40, 40, 40)
Me.ForeColor = Color.FromArgb(100, 255, 255, 255)
The result of any of these two lines is exactly the same ( no change in alpha ). The colors take ok though.
I created 3 Forms (Form1, Form2 and Form3) and I added a button on every form. This is code for Button1 on Form1:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Form2.BackColor = Color.Red
Form3.BackColor = Color.Red
Me.Hide()
Form2.Show()
End Sub
Code for Button1 on Form2:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Close()
Form3.Show()
End Sub
Code for Button1 on Form3:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Close()
Form2.Show()
End Sub
Now, the problem is that when I click on Button1 on Form3 it shows Form2 but the Form2 BackColor is not red, it is default color, A.K.A Control Color. But I specified in Button1 on Form1 that Form2.BackColor is Red. And also if I click on Button1 on Form2 when Form3 shows it, the Form3 BackColor is also default, it is not red.
I know one way to solve it but it is so not-professional. It is that you add on Button1 on Form2 this:
Form3.BackColor = Color.Red
and on Button1 on Form3 this:
Form2.BackColor = Color.Red
It is ok in this situation but what if I have more stuff, for example if I have an option for changing theme so it has to change all labels and buttons ForeColor, what then, is there any other way?

View 3 RepliesIs there an "easy" way to change a control's ForeColor when it is diabled? Yes, I know that this goes against the Windows standard.
On our forms, we have buttons with a dark blue background and a white foreground (the design is dictated by marketing). When the buttons become disabled, the ForeColor goes to a dark color making the button unreadable.

Using VB/VS 2010 and am trying to provide the user with a way to change the color of the control buttons on my main windows form. I'm starting with the button click event that then calls another sub-form (code shown respectively below).
I was testing with DirectCast as I need to deal with a multitude of button controls (i.e., will have more than the two shown below).
I would like to know how to deal with the following:
1. How do I save the BackColor so when the user opens the form for the first time (or any other time thereafter) the color set earlier appears (the default via properties is green).
2. When I click on the button for the first time and change the color it doesn't change until I click the button again.

I am new to Visual Basic 2010, but I have been trying to make a line reader with an imported text document into a RichTextBox through an internet source.
I want the RichTextBox's line zero (the first line) to really be line one, but without changing the text in the TextBox to show the change. In other words, I want that change to happen in the background of the program.
I have tried... taking the text from one TextBox and putting it into another, while subtracting an integer value of onean attempt to use a timer to copy the text from one TextBox to another to read the line properly.
I have tried a couple of other things too, but most of them were much more complicated and I could not really explain what each thing did.[code]...

Is there a more efficient/easier way changing the backcolor of a control when it has focus and lost focus? Let's say I've got 10 text boxes. Right now I would have 20 different events...10 for Enter event and 10 for Leave event. Of course, entering would change the back color to "green" and leaving would change it back to "white".
